Abstract: A see-through display apparatus includes a display device, and an optical coupler configured to obtain a combined image by combining a first image from the display device with a second image from a path different from a path of the first image, and emit the obtained combined image. The optical coupler includes a first surface on which the first image is incident, a second surface on which the second image is incident, and an exit surface through which the combined image is emitted. A noise reduction prism is disposed between the display device and the optical coupler, and includes inclined surfaces configured to perform path conversion so that, among light of the first image, effective light of a predetermined angle range is incident on the optical coupler and noise light of a remaining angle range remaining from the predetermined angle range is not incident on the optical coupler.
